ALARM.

Specification of Letters Patent.

Patented Feb. 8, 1916;

Application filed March 10, 1914. Serial No. 828,815.

To all whom z't may concern: Be it known that I, JOHN J. GREYTAK,citizen of the United States, residing at Great Falls, in the county'ofCascade and State of- Montana, have invented certain new and usefulImprovements in Alarms, of which the following is a specification.

This invention relates to an improved audible alarm device for valises,Satchels,

and such like articles. I

The object of the invention is to provide a valise, satchel or otherarticle with an alarm or signal device which will remain quiet orinoperative while the satchel is resting on the floor, table or othersupporting structure, but will automatically sound when the valise israised from its support.

The device is intended for use when the owner desires to set the valisedown in a public place and leaveit unattended for a Under suchcircumstances, if any unauthorized person should raise the valise, tocarry it oil, the alarm would sound and the owner thereof warned in timeto prevent the contemplated or attempted theft.

The above and additional objects are accomplished by such means as areillustrated in their preferred embodiment in the-accompanying drawings,described in the followng specification and then more particularlypointedout in the claim which is appended hereto and forms a part ofthis applicatlon.

In describing my invention in detail reference will be had to theaccompanying drawings wherein like characters denote like orcorrespondin parts throughout the seversial views,1and in which 1 igureis a perspective view, part y broken awa of a valise, said valise havingthe alarm evice arranged therein; Fig. 2

is a fragmentary sectional view illustrating the drawin s, I'des1re tocall particular atin detail the construction of one of the circuitbreakers employed in connection with the present invention; and Fig. 3is a similar view, the circuit being closed.

Before proceeding with the description of tention to t e fact that whileI have evolved my invention with reference to its applicasignal in thepresent instance is operated by an electric battery 2, secured to theinterior wall of the valise. The circuit wires 3 include in the circuita suitable hell or buzzer 4 of any well known type, a lock 5,

of the key operated type'and a plurality of circuit breakers designatedeach, as an entirety by the numeral 6, said circuit break-l ers beingdisposed, one adjacent each of the four corners of the valise, toextend, in a manner to be hereinafter fully described, through thebottomthereof.

The several circuit breakers 6 bein the same, but one will be describedin etail, thevsame comprising acaster 7 havin a stem 8 integraltherewith and extending into the interior of the valise throu h anopenin 9 in the bottom thereof. Sai stem 8 is en arged as at 10, theenlarged portion thereof frictionally engaging a suitable housing orcasing 11 rigid with the valise,

The stem proper 8 operates within an opening 12 of the casing 11 andhassecured thereto as indicatedat 13 a contact plate or element 14, a stripof insulation being inter posed between the said plate and the said stemwhereby to break the electric circuit clearly illustrated in Fig. 3 ofthe draw in s.

igid with the casing 11 at one side there of and in the path of thecontact plate 14 is a suitable contact '16, one of the circuit wires 3being connected thereto. U on the opposite side of the said casing 1 isanother contaQ 17, said latter contact bein also in the path of thecontact plate 14 an insulated from the said casin for an obviouspurpose. One of the sai circuit wires 3 is connected to this, the'saidlast mentioned. contact thereby providing, upon movement of the plate14, for the 616.1118

of the electric circuit whereby to sound the bell or buzzer 4.

. The lock mechanism indicated at 5 may be of any suitable key operatedtype, and in the present instance, is adapted to close the circuit uponthe locking of the valise. When unlocked, the circuit-is adaptedto bebroken. By disposing one of the circuit breakersG, (each beingelectrically connected with the battery 2) adjacent each of therespective four corners of the valise, it is apparent that the same willprovide a sup port for the valise, the casters 7 being in directengagement with the supporting structure. The weight of the valise issuificient to counteract the resistance of the several springs and causecasters 7 to come into contact with the valise bottom, and the con- 17as illustrated to advantage in Fig. 2, The electric circuit being brokenthe alarm will remain quiet, but only so long as the valise remainsunmoved. A raising or lifting of the valise until casters 7 disengagethe support, will allow springs 15 to expand and 1 'move contacts 14into engagement with contacts 16 and 17, such engagement closing theelectric circuit and automatically sounding the alarm. A furtheradvantage is obtained by the disposition of the circuit breakers 6 inthe respective corners of the valise, as it is apparent that uponopening the valise,

- and moving the cover upon its'hingesgeither one or the other side ofthe valise is raised of the said valise causing one or more of i thecasters 7 to be disengaged and the alarm sounded without bodily movingthe said valis e from its support.

. From the foregom'g, taken in connection with the accompanying drawingsit will be noted that the circuit wires are so arranged as to provldefor. the sounding of the alarm in the event of the disengagement of butone of the casters from its support; that the alarm may be renderedineffective by operation of the lock indicated at 5; and that tactplates 14L to disengage contacts 16 and during such opening operation,the raising Witnesses;

that the form of my invention, illustrated in the drawings and referredto in the above description, as the preferred embodiment, is the mostefficient and practical; yet realiz ing that the conditions concurrentwith the adoption of my device will necessarily vary,

I desire to emphasize the fact that various minor chan es in details ofconstruction, proportion and arrangement-of parts may be resorted to,when required, without sacrificing any of the, advantages of myinvention, as defined in the appended claim.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

A circuit closing device for use in connection with movable objectscomprising an open tubular casing secured to said object, a flangepartially closing one end of said casing, a movable support for saidobject fitting said casing and projecting beyond the ends thereof, anenlargement formed on one end of said support for contact with saidobject to limit movement of said support,

a spring embracing said support and abut-' ting said enlargement andsaid partially closed end of the casing to move said enlargement out ofengagement with said support upon movement of said object, diametricallyopposed fixed contacts disposed eXteriorly of said casing, and a contactsecured to said support and movable therewith into engagement with saidfixed contacts through action of said spring to close the electricalcircuit, substantially as described.

In testlmony whereof I affix my slgnature' in presence of two witnesses.
